THE BORG SERIES

Resistance is futile. PiBorg’s Borg series consists of three robots: the DiddyBorg ($294), the MonsterBorg ($294), and the YetiBorg ($224). The DiddyBorg’s flat top makes it possible for all kinds of things to be mounted atop it. A terrifying robot claw, for example. It can be reconfigured with the Multifunction Top to fit an additional Pi, or with the Touch Top to fit the official Raspberry Pi touchscreen. It can also be fitted with front and rear Pi Cameras, as well as ultrasonic sensors for obstacle avoidance.

Then there’s the MonsterBorg, a machine not to be trifled with. Its chunky four-inch wheels enable it to chew up off-road terrain. PiBorg organizes the Formula Pi racing event ( www.formulapi. com), and racing is what the MonsterBorg does best. Its 3mm-thick aluminum chassis ensures that it can survive all but the messiest of crashes.

Finally, there’s the nimble YetiBorg. Powered by a Pi Zero (included) and a single 9V battery, the YetiBorg uses the custom ZeroBorg motor controller. This enables independent control of its four motors. It can be assembled in two different configurations: low-profile and off-road. In low-profile mode, should it accidentally flip over, it’s perfectly capable of continuing upside down. If a little more clearance is required, the off-road mode keeps the chassis clear of bumps and the electronics shielded from puddles.
